Micromechanical Analysis of In-Plane Constraint Effect on Local Fracture Behavior of Cracks in the Weakest Locations of Dissimilar Metal Welded Joint

引用

Acta Metallurgica Sinica(English Letters) 2017年第9期30卷 840-850页

作者： jie yang School of Energy and Power Engineering University ofShanghai for Science and TechnologyShanghai 200093China

In this work, a set of GTN （Gurson-Tvergaard-Needleman） parameters of the Alloy52M dissimilar metal welded joint （DMWJ） have been calibrated, and a micromechanical analysis of in-plane constraint effects on the local fracture behavior of two cracks, which located in the weakest regions of the DMWJ, has been investigated by the local approach based on the GTN damage model. The results show that the partition of the material and the variation of the q2 parameter make the J-resistance curves obtained by numerical simulations close to the experimental values. The numerical J-resistance curves and crack growth paths are consistent with the experiment results, which show that the GTN damage model can incorporate the in-plane constraint effect. Furthermore, after the stress, strain and damage fields at the crack tip during the crack propagation process have been calculated, and the change of the J-resistance curves, crack growth paths and fracture mechanism with in-plane constraint have been analyzed.

Dissolved and Particulate Dimethylsulfoxide in the South China Sea During Winter

引用

Journal of Ocean University of China 2018年第6期17卷 1343-1351页

The distributions of particulate and dissolved dimethylsulfoxide(DMSOp, DMSOd) were studied for the first time in the surface water of the South China Sea(SCS) in January 2010. The concentrations of DMSOp ranged from 2.6 to 56.8 nmol L^(-1) with an average of 11.1 ± 2.2 nmol L^(-1), and those of DMSOd ranged from 11.8 to 335.1 nmol L^(-1) with an average of 50.0 ± 16.5 nmol L^(-1). DMSOd dominated over both dimethylsulfide(DMS) and dissolved dimethylsulfoniopropionate(DMSPd) by 1–3 orders of magnitude and represented the major dissolved dimethyl sulfur pool. In addition, DMSOp/chlorophyll-a ratios varied from 2.7 to 180.7 mmol g^(-1) with an average of 30.5 ± 9.6 mmol g^(-1). DMSOd concentrations displayed a significant negative relationship with sea surface temperature(SST) and sea surfaces salinity(SSS) in the whole study area. The distribution of DMSOd in the coastal waters was obviously influenced by the Pearl River discharge, with high concentrations appearing around the river mouth. In the offshore waters, a significant correlation was observed between the DMSOp and DMSOd concentrations, suggesting that DMSOd was mainly from the diffusion of intracellular DMSO rather than from the photochemical and biological oxidation of DMS.

Mechanical formula for the plastic limit pressure of stent during expansion

引用

Acta Mechanica Sinica 2009年第6期25卷 795-801页

作者： jie yang Nan Huang School of Mechanics and Engineering Southwest Jiaotong University 610031 Chengdu China School of Material Science and Engineering Southwest Jiaotong University 610031 Chengdu China

The mechanics of cardiovascular stents during the process of expansion are very important for stent function and safety. In general, finite element method （FEM） or experi- ments are major methods used to ascertain mechanical prop- erties of the stent. In this paper, we develop a theoretical model of the tubular stent, derive formulas for the axial forces and moments on the stent end, and propose formu- las for the plastic limit pressure vs. the stent＇s radius during expansion. Examples covering different geometrical param- eters and material parameters are provided, and the plastic limit pressures calculated by FEM and the present method are compared, proving that the present formulas are acceptable and meaningful for the design and innovation of the stent.

Nonnegative matrix factorization with Log Gabor wavelets for image representation and classification

引用

Journal of Systems Engineering and Electronics 2005年第4期16卷 738-745页

作者： Zheng Zhonglong yang jie Inst. of Image Processing and Pattern Recognition of Shanghai Jiaotong Univ. Shanghai 200030 P. R. China

Many problems in image representation and classification involve some form of dimensionality reduction. Nonnegative matrix factorization （NMF） is a recently proposed unsupervised procedure for learning spatially localized, partsbased subspace representation of objects. An improvement of the classical NMF by combining with Log-Gabor wavelets to enhance its part-based learning ability is presented. The new method with principal component analysis （PCA） and locally linear embedding （LIE） proposed recently in Science are compared. Finally, the new method to several real world datasets and achieve good performance in representation and classification is applied.

Convergence error estimates of the Crank-Nicolson scheme for solving decoupled FBSDEs

引用

Science China Mathematics 2017年第5期60卷 923-948页

作者： LI yang yang jie ZHAO WeiDong College of Science University of Shanghai for Science and Technology School of Mathematics Shandong University

In this work, we theoretically analyze the convergence error estimates of the Crank-Nicolson （C-N） scheme for solving decoupled FBSDEs. Based on the Taylor and ItS-Taylor expansions, the Malliavin calculus theory （e.g., the multiple Malliavin integration-by-parts formula）, and our new truncation error cancelation techniques, we rigorously prove that the strong convergence rate of the C-N scheme is of second order for solving decoupled FBSDEs, which fills the gap between the second-order numerical and theoretical analysis of the C-N scheme.
